Year 3 have been learning about the process of ‘dissolving’ in their science lessons this week. A concept that many of the pupils were familiar with before the lesson, but that not all would have given any real thought to… until now!

Gathering granular substances that are commonly found around the home (for example, sugar, salt, hot chocolate powder, flour, sand or ground pepper) the pupils carried out tests to find out how soluble each substance was when mixed with water. They were also asked to observe any differences in the rate at which each substance dissolved when carrying out the test using cold and then warm water.

A simple way to engage children in conducting their own scientific investigations at home, this task resulted in some brilliant graphs and excellent concluding paragraphs when the children wrote up their results.
